A locking member is mounted to the housing to be able to move in the outer diameter direction by a tapered portion of the tubular body, when the tubular body is inserted. The housing is equipped with slits formed to pass a curved portion bent in the inner diameter direction disposed at a leading-end side of the locking member and to lock with the engagement portion of the tubular body mounted on the housing. A gap is disposed between the curved portion, and the end portion of the slit positioned at a side in an opposite direction to the leading-end side of the locking member, so that there is no contact while at least the locking member is moving.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a sterile connection for drug delivery. In some embodiments, the fluid coupling devices can be implemented as multi-use, sterile fluid coupling devices that are configured to reduce the likelihood of fluid spillage when being disconnected.

The utility model relates to a household submersible pump, which comprises a pump base, a pump body and a signal light assembly, wherein the pump base is provided with a water outlet, a water inlet and a first filter screen; the pump body has an inner housing having an inner electrical chamber equipped with a circuit board therein and a front mount, and an outer housing having a front guiding seat; the signal light assembly comprises a signal light connected to the circuit board and a light guiding column with a waterproof seal ring embedded therein; the light guiding column is able to be rotated from a first state in which it can be inserted into the front mount through the front guiding seat to a second state in which it is locked in the front mount, and is set to be able to export the light emitted from the signal light to the outside of the outer housing. The utility model not only achieves an outward propagation of light to indicate the status of the pump but also achieves an IPX8 level waterproof.

A connection device for connecting a tubular connector provided with an annular collar to an item of equipment comprising a passage, the connection device comprising:—a connection end fitting connecting to the passage of the item of equipment, the connection end fitting being formed by a tubular body with a head mounted thereon, the head being provided with a through-opening and comprising an ellipsoidal annular groove;—a locking ring having at least two longitudinal flexible legs for insertion into the connection end fitting, each having an outer surface bearing at least one lug intended to engage in the annular groove in order to hold the locking ring secured to the connection end fitting. The two flexible legs can be deformed and closed on the tubular connector in order to abut their free ends against the collar when the male connector is inserted longitudinally into the locking ring.

A verification pull tab clip includes a pull tab. A generally planar body extends from the pull tab and has first and second opposite sides, proximal and distal ends, and top and bottom ends. The body is elongated in a longitudinal direction that extends between the proximal and distal ends. An indication surface is disposed on the first side of the body. A cantilevered arm extends from the pull tab in the longitudinal direction and is spaced apart from the body. The arm terminates at a free end and has first and second sides. A latch is disposed at the free end of the arm. An abutment projects outwardly from the second side of the arm. The arm is deflectable away from the bottom end for securing the latch, and is deflectable away from the bottom end for releasing the latch in response to a deflection of the abutment.

This document describes fluid handling couplings. For example, this document describes fluid handling couplings that are genderless, that include manually openable valves, and that are configured for single-use aseptic fluid handling usage.

A damper for an exhaust duct of an exhaust line of a semiconductor fabrication apparatus includes a damper body to be inserted into a fixing hole in the exhaust duct in a first direction, the damper body having a diameter substantially the same as a diameter of the fixing hole, and plural push buckles. The push buckles are provided on a distal end of the damper body along an outer circumferential surface of the damper body and spaced apart from each other around a circumference of the damper body, the push buckles being resilient and movable with respect to the outer circumferential surface along a second direction perpendicular to the first direction. When the push buckles have passed through the fixing hole in the first direction, the push buckles prevent a return movement through the fixing hole in a direction opposite to the first direction.
